Chisato and Maimai talking about the same thing. In their era, HP kid scare shitless of elder MM and elder club (I look at you Nakazawa and Ishikawa). Now Kudo and Sato are "hey it meeting time, join us already" to Yankee Tanaka LoL.

^ Yep. Calling the group together for meeting time is generally the job of the senpai, or even the group's leader/captain. Someone like Duu saying it to Reina is... a bit unusual, especially given the history Tae mentions ^^;Mai's talking along that same vein
